"By analyzing the baseline pressure and temperature data throughout the stock exhaust system, Supersprint engineers determine what pipe diameter to use and where maximum performance gains can be made. At each measurement location (or exhaust component) there is a unique back pressure characteristic. The graphs on page 82 and this page show pressure characteristics at the four locations in the OEM system of the RS4 and E92 M3 respectively.

Exhaust pressures increase with revs at each point, decreasing as the exhaust moves through the system. Note that an average vehicle with a 6000-rpm redline will have a 'Pressure 1' value in the 7.3 psi range (dotted black line on each plot), while more sporting models will measure in the 3.0 to 5.5 psi range at 6000 rpm and continue to increase toward their higher redlines. The RS4 and M3 fall into this sporting/performance range and therefore have systems that are well optimized from the factory. However, the new M3 has higher Pressure 1 values, indicating a good candidate for an aftermarket header application. Incidentally, Supersprint is developing a step header for the new M3."

Well by now we all know you get what you want. Its only a matter of time before you pass the 500hp mark and with he racing seats and other weight reductions mods you will surely do, you'll be blasting past Ferrari's in no time.

I'm just waiting for you to get a a turbo or supercharger on your car. If that happens after all of these other gains you keep racking up, will be quite impressive.

I do like SCís and love turbos much better, we will see what they come up with but donít ever want to do something where I lose the carís balance. If forced induction can be done while keeping general weight distribution/performance about the same, then Iím all for it. This can probably be done with light weight materials and sending some components to the rear. Anyway, we will see. This is sometimes why a stroker kit makes so much sense in this particular case and before I have further information on the options.
